Abstract

A series of gibberellin based molecules were designed and synthesized. Gibberellin derivatives bearing two alpha,beta-unsaturated ketone units showed strong Anticancer activities in MTT assay towards a number of human Cancer cell lines including HT29, A549, HepG2 and MKN28. The most potent gibberellin derivative (compound 10, IC(50)=2.9 microM against HT29) inhibited completely the Topoisomerase I activity at 8 microg/mL level.
